Goodyear tire going bald on one edge
Folks, I have an HT 26.5 RLS that we purchased in Jan. 2012 and have used the last four summers with no tire problems. We took a 3,500 mile trip last spring as well as going to Zion and up to and back from Grand Teton National Park 12 times. However, when hooking up at the Park on Monday I noticed that the inside tread in going bald on the driver side rear tire. All the other tires look fine. The tires are Marathons, OEM on this trailer, 225 75R 15 Load Range D. I don't really want to replace all four tires so was considering buying two new Marathons and replacing the two rear tires. I haven't looked at the production dates, but they don't seem to be showing any signs of cracking or other problems associated with "old" tires. I looked at Maxxis tires, but the prices kind of scare me off, as well, we don't have any dealers for Maxis around here in the middle of Wyoming. What do you think about the idea of two tires and simply replacing both the rear tires at this time?
